In order to protect electric household appliances or their users against dangerous overvoltages caused by load variations in the network or by atmospheric discharges (lightning), a shunt element (3) field with gas and a zinc oxide varistor (4) are arranged in the casing (2) of the current connecting plug formed as an intermediary or adaptor plug, between the alveoli (1) of the plug on the appliance side, and mounted in parallel, so as to shortcircuit the connection terminals or connected between those terminals and the hearth lead. This protection assembly (3, 4) is connected on one hand directly, and on the other hand through a fuse (6) to the network connection pins (5), so as to prevent by supressing overvoltages a brake down in the network and consequently the triggering of the braker for protecting the installation against current faults. |
